Why did Vicent 'washout' in bootcamp?...
The washout rate in Marine bootcamp during wartime is small as the corps needs "warm bodies." I went through Marine bootcamp in 1967 and out of around 75 guys only three were discharged. Those that were discharged were cut out in the first weeks and seemed to have emotional issues that the recruiter didn't catch or covered up. We had one guy who had some type of cognitive problem where the simpliest order could not be handled by him. He was released around training day three.
Was Vincent discharged during of after bootcamp? I have seen this movie in over twenty years. (I recommend Dogfight and Stateside for anyone who enjoys a story with young Marines in it.)
